You can add "-mp=nonuma" to not link with the NUMA library or determine why the linker can't find the library.

Often systems have "/usr/lib64/libnuma.so.1" but just need a symbolic link "/usr/lib64/libnuma.so -> /usr/lib64/libnuma.so.1" added in order to resolve this library. However, during installation of the compilers if the installer doesn't detect that your system have "libnuma.so" available, a PGI supplied dummy NUMA library will be included in your PGI installation directory. Why this dummy library wouldn't have been added to your installation is unclear.

But now I have a new " link error":
/fftw-3.3.3/lib/libfftw3_omp.a(libfftw3_omp_la-openmp.o): In function `fftw_spawn_loop':
openmp.c:(.text+0x10f): undefined reference to `GOMP_parallel_start'
openmp.c:(.text+0x11c): undefined reference to `GOMP_parallel_end'
make: *** [GP2DS_OPENMP] Erreur 2

Due to fftw 3.3.3.
So does it mean that I need to rebuilt a fftw with PGI compiler, right ?
